Abstract: An exercise apparatus comprising a base; a supporting surface carried by the base, the supporting surface to receive a weight bearing portion of a user's body; a support frame carried by the base; a stationary pelvic belt receiving frame carried by the support frame; a pelvic belt rotatably received within the stationary pelvic belt receiving frame and configured to securely receive a pelvic area of the user's body for rotation therewith; and one or more mechanical force resistors carried by the support frame and operably coupled to the pelvic belt so as to impart resistance to rotation of the pelvic belt relative to the stationary pelvic belt receiving frame.

Abstract: A torso, muscle and spine exercise apparatus. A base having upwardly extending tubes into which a handgrippable handle is attached, includes a tiltable, rotatable platform upon which a user stands. The user stands upon the platform and fastens one or more harnesses about his waist or torso. Conventional weight stacks are attached to the harness or harnesses at two or four front points and two or four rear points by a cable and pulley system. Rotation of the user's waist or trunk lifts the weights, causing resistance to rotation. The rotatable platform upon which the user stands can be tilted in any direction to rotate freely about the tilted axis. Exercise of certain portions of the spine may be accomplished by a torso stabilizer belt fastened to the handgrippable handle and extending about the user's chest or waist.
